Is it possible to determine which app is active when a alarm is activated

[Ronald Gouldner Jr]

I am writing an app that receives an alarm and launches my program 
after some processing I want to return to the previous app.

I tried saving the value of SysCurAppDatabase during the alarm triggered
event but this call seems to return the app receiving the alarm triggered
not the "real" current app database.

Does anyone have any tips on how to determine the current UI app ?
